Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Assessments will be conducted by two researchers (JD and GE). The participant will be given a participant number. A list of participant numbers will be made in advance and linked to a set of random numbers (1= treatment; 2 = wait-list) generated by randomizer.org. The randomization schedule will be held by the chief investigator who will not have had any direct contact with the children. The randomization schedule will remain concealed until allocation. Once the children complete the baseline assessment, the randomization code will be broken for that participant and they will be informed of the group to which they have been allocated.
